Hi,


I got this error when trying to connect to a s57200 switch with ssh :

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Someone could be eavesdropping on you right now (man-in-the-middle attack)!

It is also possible that a host key has just been changed.

The fingerprint for the RSA key sent by the remote host is

SHA256:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.

Please contact your system administrator.

Add correct host key in /root/.ssh/known_hosts to get rid of this message.

Offending RSA key in /root/.ssh/known_hosts:293

  remove with:

  ssh-keygen -f "/root/.ssh/known_hosts" -R 10.X.X.X

RSA host key for 10.X.X.X has changed and you have requested strict checking.

Host key verification failed.


Any idea how to resolve this please ?

Thank you.

Hi user_3606116,

Just edit ~/.ssh/known_hosts and delete line 293, as the message pointed you:

Offending RSA key in /root/.ssh/known_hosts:293


or use ssh-keygen to delete the invalid key

 ssh-keygen -R "the server hostname or ip"
